You can even auto-spin your content selectively using The Best Spinner.

Proxies
Add as many proxies as you like, or load proxies from a text file on another server – maintain a central proxy list from one place; all your SocialBacklinker Pro installations can share one list.

Content fuzzing
Post related content to your accounts. Make the accounts look more human instead of just posting content that links back to your own sites. Avoid the ban hammer!
